Description

Technical Field

[0001] This utility model relates to the field of cable protection pipe technology, specifically an anti-aging cable protection pipe. Background Technology

[0002] Cable protection pipes are metal protective pipes with a certain mechanical strength that are laid on the outer layer of cables to prevent them from being damaged.

[0003] Cable protection pipes are mainly installed at the intersection of communication cables and power lines to prevent short circuits caused by power line breaks, which could lead to energization of communication cables and steel wire ropes. This protects cables, switches, circuit boards, and even the entire device from being burned out. They also provide some isolation against magnetic field interference from power lines.

[0004] However, existing cable protection pipes still have certain drawbacks in actual use. Since the protection pipes need to be laid in the soil, once there is heavy rainfall or the soil around the pipe collapses due to excessive pressure from the external frame, the entire protection pipe will break, which will then damage the cable.

[0005] In view of this, an anti-aging cable protection pipe was designed to solve the above problems. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0026] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an anti-aging cable protection pipe.

[0027] Example 1:

[0028] Combination Figures 1 to 4 As shown, the present invention provides an anti-aging cable protection pipe, including a cable 100, a protection pipe assembly 200 disposed outside the cable 100, and a side-bending protection assembly 300 installed on the protection pipe assembly 200. The protection pipe assembly 200 is used to provide sealing protection for the laid cable 100, and the side-bending protection assembly 300 is used to buffer and reduce pressure on the pressure-bearing parts of the protection pipe assembly 200 to avoid the protection pipe assembly 200 from breaking due to excessive pressure.

[0029] The protective pipe assembly 200 includes a protective head pipe 210 and a protective tail pipe 220, and two side-bend protective pipes 240 are provided between the threaded sections of adjacent protective head pipes 210 and protective tail pipes 220.

[0030] The protective tube assembly 200 also includes a first ring washer 230, two first screws 2301 movably mounted in the first ring washer 230, a first slider 2302 movably mounted on the threaded section of the first screw 2301, a first lever arm 2303 movably mounted on the first slider 2302, and a first ring buckle 2304 movably mounted on the other end of the first lever arm 2303.

[0031] Both the first ring buckle 2304 and the second ring buckle 2405 are composed of an arc-shaped stainless steel inner pad and a rubber outer layer.

[0032] The side bending protection assembly 300 includes two adapter ends 310, a corrugated hose 320 fixedly installed between the two adapter ends 310, and a slot is provided on the inner side of the adapter end 310, and a traction frame 350 is movably installed in the slot.

[0033] A second connector 340 is movably installed at one end of the traction frame 350, and a first connector 330 is movably installed at the other end of the traction frame 350.

[0034] A sealing ring is fixedly installed on the inner wall of the adapter end 310.

[0035] One set of side-bending protection components 300 is installed on the threaded section of the protective head pipe 210, another set of side-bending protection components 300 is installed on the threaded section of the protective tail pipe 220, and a third set of side-bending protection components 300 is installed between the two side-bending protective pipes 240. At this time, the two side-bending protective pipes 240 and the three sets of side-bending protection components 300 can provide side-bending protection for the parts of the cable 100 that are under pressure and deformed. While reducing the pressure on the pipeline caused by soil collapse, it can also prevent the cable 100 from being broken or worn due to pipeline deformation.

[0036] Example 2:

[0037] Combination Figure 4 As shown, based on Embodiment 1, a second ring gasket 2401 is fixedly installed in the middle of the inner cavity of the side-bending protective tube 240, two second screws 2402 are movably installed at both ends of the second ring gasket 2401, a second slider 2403 is movably installed on the threaded section of the second screw 2402, a second lever arm 2404 is movably installed on the second slider 2403, and a second ring buckle 2405 is movably installed on the second lever arm 2404;

[0038] The inner walls at both ends of the side-bending protective tube 240 are provided with grooves, and the grooves in the two side-bending protective tubes 240 are distributed vertically between the three sets of side-bending protection components 300.

[0039] After the protective tube assembly 200 and the three sets of side-bending protection assemblies 300 are assembled, once the part is compressed, one of the side-bending protective tubes 240 will be misaligned in the vertical direction, while the other side-bending protective tube 240 will be misaligned in the horizontal direction. During the misalignment of the two side-bending protective tubes 240, the three sets of side-bending protection assemblies 300 will stretch relative to each other, so as to cooperate with the deformation of the side-bending part of the cable 100.

[0040] The working principle and usage process of this utility model are as follows: According to the requirements of the cable 100 layout, a trench is opened in the ground as required. Then, the protective head pipe 210 and the protective tail pipe 220 are laid along the trench in the ground. Then, the cable 100 is inserted into the inner cavity of the protective head pipe 210. Then, two side-bend protective pipes 240 are set between adjacent protective head pipes 210 and protective tail pipes 220. The two side-bend protective pipes 240 are installed on the protective head pipe 210 and the protective tail pipe 220 respectively by three sets of side-bend protection components 300 until the protective pipeline forms a whole. The cable 100 will cross to the middle of the inner cavity of the protective pipeline.

[0041] After the cable 100 is laid in the trench on the ground through the protective pipeline, the cable 100 in use can be effectively protected. If the ground collapses due to heavy rainfall or external force, the three sets of side bending protection components 300 can misalign the pipeline to a certain extent, so as to avoid the overall breakage of the protective pipeline due to excessive pressure from the collapse of the ground.

[0042] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
